Augmentation of weld penetration by flux assisted TIG welding and its distinct variants for oxygen free copper
نویسندگان
چکیده
A comparative study to investigate the influences of single component fluxes on depth-to-width ratio (DWR) oxygen free copper was carried out with novel variants tungsten inert gas (TIG) welding namely Activated TIG (A-TIG), Flux Bounded (FB-TIG) and Zoned processes. The experiments identify delivering higher DWRs in A-TIG among thirteen distinct were followed by trials FB-TIG FZ-TIG employing those identified DWR fluxes. which outperformed all techniques MoO3 & MgO. Reversed Marangoni arc constriction mechanisms perceived be opt for such an increase DWR. Metallurgical characterization weldment indicated grain morphologies certain defects as well weld zones. is postulated surpass terms bringing about upmost penetration.

Structure-property Interaction in Flux Assisted Tungsten Inert Gas Welding of Austenitic Stainless Steel
Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...
متن کاملPrediction of the weld pool geometry of TIG arc welding by using fuzzy logic controller
The present paper describes fuzzy logic simulation of tungsten inert gas welding (TIG) process to predict the weldment macrostructure zones' shape profile characteristics. The prediction of the weld pool geometry together with the shape of the heat affected zone (HAZ) was accomplished taking into account of TIG welding process parameters such as arc traverse speed, welding current and arc lengt...
متن کاملThe effect of activating fluxes on 316L stainless steel weld joint characteristic in TIG welding using the Taguchi method
Gas tungsten arc welding is fundamental in those industries where it is important to control the weld bead shape and its metallurgical characteristics. However, compared to the other arc welding process, the shallow penetration of the TIG welding restricts its ability to weld thick structures in a single pass (~ 2 mm for stainless steels), thus its productivity is relativity low. This is why th...
متن کاملEffect of welding parameters on penetration depth in FB-TIG welding of 5083 aluminum alloy
In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
